Hi Captain, concerning your on/off switch, if you disconnect one wire,place an ohmmeter across the terminals and try the switch just to confirm it isn't operating. You can look and see if there is any opening at all to the interior of the switch and try and spray some contact cleaner into it. If there is no apparent opening, one thing I've had luck with is using a very thin drill and gingerly try and drill a hole through the plastic while trying to make sure you only drill through without penetrating to the interior. Then you can spray some contact cleaner in. It is a last resort thing to try as you have nothing to lose at this point and could save you from needing to find a replacement!
